The BAppFileInfo class allows for information about an executable or add-on to be accessed or set. Information about an executable that can be accessed include the signature, catalog entry, supported MIME types, application flags, icon(s), and version info. You should initialize the BAppFileInfo with a BFile object that represents the executable or add-on that you want to access. If you only want to read metadata from the file you do not have to open it for reading. However, if you also want to write metadata then you should open the BFile for writing. To associate a BFile with a BAppFileInfo object you can either pass the BFile object into the constructor or you can use the empty constructor and then use the SetTo() method to set the BFile to the BAppFileInfo object. When accessing information from a BFileInfo object it will first look in the attributes of the BFile. If the information is not found then the BFileInfo object will next look at the resource of the BFile. You can tell the BFileInfo object to look only in the attributes or resources with the SetInfoLocation() method. \since BeOS R3 */ /*! \fn BAppFileInfo::BAppFileInfo() \brief Creates an uninitialized BAppFileInfo object. \since BeOS R3 */ /*! \fn BAppFileInfo::BAppFileInfo(BFile* file) \brief Creates an BAppFileInfo object and initializes it to the supplied file.
